My fiancé and I have this issue but opposite all the time, it’s not an easy discussion, but we have it all the time. I became (and still become) upset because I feel like the only time he’s affectionate toward me is when he wants sex and it felt unfair so I stopped wanting sex because the affection became a turn off. I held it in for a long time and naturally because I was upset by it, he was more upset being “blind sided”. We established better communication and it got a lot better. Sometimes there’s a “relapse” but we always talk it though. So, just like everyone else is saying, do your best OP to communicate that laying and cuddling is just as intimate and important as the sexual portion. Good luck OP!
